LuK Dual Mass Flywheel with Centrifugal Pendulum-type Absorber
This small component means big fuel savings
After its success in developing the dual-mass flywheel (DMF), LuK set another milestone in vibration damping technology by integrating a centrifugal pendulum-type absorber (with no increase in component size). This increases its damping capacity by a further engine-speed adaptive component.
In a DMF, the flywheel contains two masses which can be turned against each other by up to 120° using a bearing. Both masses are connected by an efficient spring-damper system. By adding a centrifugal pendulum-type absorber, damping performance is increased even further. With it, new engine concepts can realize their potential for fuel and CO2 reduction, while retaining high levels of driving comfort.
What the centrifugal pendulum-type absorber does is simple – its spring-loaded, oscillating masses vibrate in opposition to the torsional vibration of the engine, which are especially strong at low engine speeds.
The energy caused by rotational irregularities, therefore, is completely absorbed by the pendulum. And this reduces drivetrain vibration.
- Prevents noise and vibration in the drivetrain
- Long service life
- Allows comfortable driving at very low engine speeds
- Reduces CO2 emissions and fuel consumption
- LuK is the first supplier of vehicle applications with centrifugal-force pendulums and Schaeffler Automotive Aftermarket supplies these to the spare-parts market
